Measure and graphically display a system's frequency response
If you're using an updated Helix digital signal processor, Helix now includes a real-time analyzer (RTA) app in their DSP PC-Tool software. Helix's MTK-1 Measurement Tool Kit allows you to measure and display your system's frequency response on your laptop. This kit comes in a handy plastic carrying case and includes a reference measurement microphone, an XLR-USB module with phantom power, a USB memory stick loaded with test signals and software, plus all the cables you'll need to connect them to your laptop.
The reference microphone and other accessories fit into this handy carrying case.
Perfect for an installer
If you're an installer who uses Helix DSPs in your customers' systems, Helix provides several target response curves designed for different vehicles. You can set up the desired curve in the background of the RTA display so you can easily adjust the DSP to match that response. The differences between the target curve and the system's true response are also shown to help you zero in your tuning.
